The Constitution of Florence offered many points of weakness to the attacks of such intriguers. In the first place it was in its origin not a political but an industrial organisation—a simple group of guilds invested with the sovereign authority. Its two most powerful engines, the Gonfalonier of Justice and the Guelf College, had been formed, not with a view to the preservation of the government, but with the purpose of quelling the nobles and excluding a detested faction. It had no permanent head, like the Doge of Venice; no fixed senate like the Venetian Grand Council; its chief magistrates, the Signory, were elected for short periods of two months, and their mode of election was open to the gravest criticism. Supposed to be chosen by lot, they were really selected from lists drawn up by the factions in power from time to time. These factions contrived to exclude the names of all but their adherents from the bags, or borse, in which the burghers eligible for election had to be inscribed. Furthermore, it was not possible for this shifting Signory to conduct affairs requiring sustained effort and secret deliberation; therefore recourse was being continually had to dictatorial Commissions. The people, summoned in parliament upon the Great Square, were asked to confer plenipotentiary authority upon a committee called Balia, who proceeded to do what they chose in the State, and who retained power after the emergency for which they were created passed away. The same instability in the supreme magistracy led to the appointment of special commissioners for war, and special councils, or Pratiche, for the management of each department. Such supplementary commissions not only proved the weakness of the central authority, but they were always liable to be made the instruments of party warfare. The Guelf College was another and a different source of danger to the State. Not acting under the control of the Signory, but using its own initiative, this powerful body could proscribe and punish burghers on the mere suspicion of Ghibellinism. Though the Ghibelline faction had become an empty name, the Guelf College excluded from the franchise all and every whom they chose on any pretext to admonish. Under this mild phrase, to admonish, was concealed a cruel exercise of tyranny—it meant to warn a man that he was suspected of treason, and that he had better relinquish the exercise of his burghership. By free use of this engine of Admonition, the Guelf College rendered their enemies voiceless in the State, and were able to pack the Signory and the councils with their own creatures. Another important defect in the Florentine Constitution was the method of imposing taxes. This was done by no regular system. The party in power made what estimate it chose of a man's capacity to bear taxation, and called upon him for extraordinary loans. In this way citizens were frequently driven into bankruptcy and exile; and since to be a debtor to the State deprived a burgher of his civic rights, severe taxation was one of the best ways of silencing and neutralising a dissentient.
I have enumerated these several causes of weakness in the Florentine State-system, partly because they show how irregularly the Constitution had been formed by the patching and extension of a simple industrial machine to suit the needs of a great commonwealth; partly because it was through these defects that the democracy merged gradually into a despotism. The art of the Medici consisted in a scientific comprehension of these very imperfections, a methodic use of them for their own purposes, and a steady opposition to any attempts made to substitute a stricter system. The Florentines had determined to be an industrial community, governing themselves on the co-operative principle, dividing profits, sharing losses, and exposing their magistrates to rigid scrutiny. All this in theory was excellent. Had they remained an unambitious and peaceful commonwealth, engaged in the wool and silk trade, it might have answered. Modern Europe might have admired the model of a communistic and commercial democracy. But when they engaged in aggressive wars, and sought to enslave sister-cities like Pisa and Lucca, it was soon found that their simple trading constitution would not serve. They had to piece it out with subordinate machinery, cumbrous, difficult to manage, ill-adapted to the original structure. Each limb of this subordinate machinery, moreover, was a point d'appui for insidious and self-seeking party leaders.
Florence, in the middle of the fourteenth century, was a vast beehive of industry. Distinctions of rank among burghers, qualified to vote and hold office, were theoretically unknown. Highly educated men, of more than princely wealth, spent their time in shops and counting-houses, and trained their sons to follow trades. Military service at this period was abandoned by the citizens; they preferred to pay mercenary troops for the conduct of their wars. Nor was there, as in Venice, any outlet for their energies upon the seas. Florence had no navy, no great port—she only kept a small fleet for the protection of her commerce. Thus the vigour of the commonwealth was concentrated on itself; while the influence of the citizens, through their affiliated trading-houses, correspondents, and agents, extended like a network over Europe. In a community of this kind it was natural that wealth—rank and titles being absent—should alone confer distinction. Accordingly we find that out of the very bosom of the people a new plutocratic aristocracy begins to rise. The Grandi are no more; but certain families achieve distinction by their riches, their numbers, their high spirit, and their ancient place of honour in the State. These nobles of the purse obtained the name of Popolani Nobili; and it was they who now began to play at high stakes for the supreme power. In all the subsequent vicissitudes of Florence every change takes place by intrigue and by clever manipulation of the political machine. Recourse is rarely had to violence of any kind, and the leaders of revolutions are men of the yard-measure, never of the sword. The despotism to which the republic eventually succumbed was no less commercial than the democracy had been. Florence in the days of her slavery remained a Popolo.
